Ricardo Zúñiga, White House special envoy for the Northern Triangle, said Thursday that the list was not final and that pulling U.S. visas from those named does not exclude the possibility of other sanctions. The law requires the State Department to provide a list to Congress at least once a year. The list was composed using classified and unclassified information and more attention was given to cases involving people currently in government or in positions close to power rather than older offenses, Zúñiga said. “Corruption and attacks on democracy are viewed as some of the most important root causes of irregular migration from Central America,” he said. “They hobble governments, they distort markets, they undercut development efforts, and ultimately they demoralize a population that decides to embark on a very dangerous irregular migration to Mexico and the United States because they don’t believe we can build their futures at home.”
